    Abandoned naval mines become more likely to explode over time, due to several factors:

    • Corrosion: The metal casings of naval mines can corrode over time, weakening the structure of the mine and making it more likely to rupture.
    • Leakage: Corrosion can also lead to leakage of the explosive material inside the mine. This can make the mine more sensitive to shock or vibration, and therefore more likely to explode.
    • Deterioration of detonators: The detonators in naval mines can also deteriorate over time, making them more likely to explode prematurely.

    Many naval mines are designed to self-destruct after a certain period of time. This is to prevent them from becoming a hazard to navigation in the future. However, the self-destruct mechanisms in these mines can also fail over time, making the mines even more dangerous.

      Ok, that was kind of what I was thinking. I know in movies and TV shows they usually are “thought of” as inert or duds, and then it always turns out they weren’t. But that also always sort if implied they must have been less likely to trigger, if there was reason for the characters in the show to believe they were inert until finding out otherwise.

      Buy yeah, in reality it always seemed to me like they must get more sensitive over time. The only way I could have maybe seen them get “safer” is if rust rendered all the contact pins immobile or something. But even if that could be the case, it still wouldn’t actually be safer, but could explain why people might initially think it was if they didn’t know.
